Vindicator Heavy Cruiser is a reduced-size version of the Imperial Star Destroyer. It is not a canon ship but there are many renderings of this ship, including my own. It was about 600 meters in length, and had a similar hull to the Interdictor cruiser from Star Wars Rebels
Also known as Vindicator Star Frigate or Vindicator Star Destroyer.
